What a Onix card is worth

The most valuable Onix on this list is Onix from Legendary Collection at $132.50, and the 32 priced copies across 31 sets are worth $481 together. Most of that sits in a handful of printings: the older the set and the scarcer the print run, the wider the gap to the rest.

If you are trying to identify which Onix you have, the set name is printed on the card and the collector number sits in the bottom corner. Open the card here and the page carries every printing of it, the graded prices, and whether grading the copy is worth the fee. Sets to start with: Legendary Collection, Aquapolis, Southern Islands.
